A 10-Year Battery for AirTag

Really neat idea and at that price I’ll probably get some for luggage and my backpacks, where I have AirTags that stay there the whole time.

One thing I’m curious about battery leakage. Many of the batteries of my remotes and similar devices seem to leak after a while (including one I heard pop and got very warm). These are devices that do get frequent usage, so they aren’t just sitting without any discharge (but also the drain for a remote would be very minimal).

Would this device experience the same, given how little power the AirTag needs?

This appears to be intended to be used with lithium primary cells.

Lithium primary cells tend not to get all leaky with age like alkalines do. (They'll keep your remote working approximately forever, too.)
